Application led April 2,

the type in which a copy plate and a line indi.- cator spanning the copy plate are mounted on a vertically extending casing plate or frame and are moved relatively to each other vby mechanical means, and in which the casing plate or frame hasa supporting arm pivotally attached thereto for movement from an inoperative position in which it extends substantially parallelA with the copy plate to an operative position in which it extends forwardly of and substantially perpendicular to the front face of the copy plate.

An object of this invention is to provide improved supporting means for a copyholder. Another obj ect is to provide improved means for mounting the casing plate or frame. Another object is to provide an improved supporting arm structure.v Another object is to provide improved means for locking theV supporting arm in its operative position.

Referring vnow to lligureY l of the drawings, there is showna copyholder comprising the usual casing plate or frame 20, copy plate 2l, line indicator 22, and paper holding clip '23. |lfhe copyholder is provided with the usual. actuating mechanism (not shown) which is controlled byan operating lever 24 pivotally mounted on an improved supportrlhe casing plate 4spot welded, as indicated at 26 in Figures 4 Cil 20 has its bottom flangeV and is spot welded to the rear face of the casing plate as indicated at 82 in Figures 2 and l0. One end oit the angle bar portion of the member has an integral flange 33 formed thereon which projects forwardly and is spot welded to a side flange oit the easing plate. The angle bar portion merges into the Z-'bar portion at its other end and the vertical leg or flange of the said angle bar forms the web of the Zbar.

The upper flange 34 of the Z-bar projects substantially horizontally forwardly in parallel relation to the upper surface of the front portion of the base plate 27, and its inner end has a vertical flange 35formed integrally therewith, which engages and' is `spot welded to a side fia-nge ofthe casing plate. The flange 34 and base plate 27 form a channel or housing for an end of the supporting arm. A channel-shaped guide member 36 is mounted between the flange 34 and base plate 27 with its web spot weldedl to t-he web of the Z-bar and its legs or flanges 37 projecting forwardly in spaced relation to the flange 34 and base plate 27.

The supporting arm 25 comprises vertical side walls 40and 41. Side wall 40 has upper walls 42 and 48 and a bottom wall 44 formed integrally therewith. The upper wall 43 merges into an end wall 45, and the end por tions of the upper wall 42 and bottom wall 44 are 'extended to form spaced hinge members 46 and 47 projecting at right angles to the side wall 46. The end edges of the hinge members 46 and 47 aie substantially parallel and they merge with and extend perpendicularly to the adjacent end edge ofthe wall 40. The hinge members 46 and 47 are pressed inwardly to form recesses or grooves 50 and 5l which have concentric openings or bores in their bottom walls.

The side wall 4l has tabs or flanges 52 formed thereon adjacent its lower edge and proj ectingsubstantially at right angles thereto. rllhe flanges 52 are provided with downwardly struck integral tongues 58 which are kadapted to project into slots` 54 in the bottom wall 44 to aid in holding the side wall 4l in its proper position relatively to the side wall 40. rlhe upper central portions of the side walls 40 and 41 are extended upwardly to form tabs 55 and 56 which are provided with slots or bores which are concentric when the supporting arm is assembler. A bolt or pin 57 extends through the apertures in the members 55 and 56 and through an aperture in the operating lever 24 and forms a pivot for the said operating lever while functioning to hold the side walls 46 and 4l in their proper relative positions to provide a suitable support.

The bottom wall 44 and end wall 45, at their juncture, are provided with open end slots. The slot in the end wall 45 is slightly larger than the slot in the bottom wall, in

order that the head of an ordinary nail or screiY projecting above a horizontal surface when its shank fits closely between the walls of the slot in the member 44, passV through the said slot and the arm may thus be locked against'vertical movement. ln order to lock the arm against horizontalinoveinent, a el-shaped latch member 60 has its side arms pivotally mounted on a horizontally extending pin 61- mounted on the side walls 40 and 4l. The web or bottom of the ULshaped member 60 is adapted to cover the slot in thee-nd wall 45 when in its lower-most position (Figure S).

A spring plunger, comprising part of the means for locking the supporting arm in its extended position, is mounted on the hinge members 46 and 47, and comprises a iin member 62 and a helical spring 63. The pin 62 is so mounted that its upper' end portion is seated for sliding movement in the aperture formed in the recess 56 and its lower end por'- tion is seated for sliding movement in the aperture formed in the recess 51. The upper end surface of the pin 62 is normally flush pin 64 also serves to limit the downward movement of the pin 62. l

l/Vhen the supporting arm is applied tothe copyholder, the hinge member 46 is inserted between the flange 34 and a flange 37 and the hinge member 47 is insertedbetween the other flange 37 and the base plate 27, and a pin 65 extends through apertures in the said flanges and hinge members and forms a `pivot about which the supportingarm. may be rotated. The pin 65 is so positioned that when the supporting arm extends substantially perpendicular to the copy plate, the end edges of the hinge members "and the side wall 40 engage the inner surface of the Z-bar web.

A button 66 having a recessed, beveled head is mounted on the base plate 27 with its head projecting above the upper surface thereof. The button 66 is positioned adjacent the web ofthe Z-bar in the path of travel of the spring plunger. As the supporting arm moves outwardly, the spring plunger moves inwardly and the tapered end of the pin 62 engages thek beveled surface of' the member 66 and moves upwardly thereon against the action of the spring 63. When the endy edges of the hinge members engage the webof the Z-bar, the center of the recess in the member 66 and the axis of the pin 62 coincide and the spring 63 moves the tapered end of the pin into the said recess, thereby locking the arm in position. Since the end of the pin 62 is tapered, pressure applied on the supporting arm in the opposite direction will cause the said pin to ride up the inner surface of the recess and the arm may thus be released. 'The recesses 50 and 5l provide clearance between the ends of the pin (32 and the flange 34: and base plate 27 during the movement of the said pin with the supporting arm. The lowersurfaee of the outer end portion of the bottom wall 44 of the supporting arm lies substantially in the same horizontal plane as the lower surface of the base plate 27.

Most of the various parts of the apparatus are preferably formed of pressed steel which adapts itself readily to spot welding.

From the foregoing it will be seen that there is herein provided an apparatuswhich embodies the features of this invention and achieves the objects thereof. An improved copyliolder structure has been provided which is thoroughly efficient and dependable in use, of strong and durable construction, and relatively simple and inexpensive to manufacture.
